Mini-Review: Samsung 40KU6400 as a monitor

ToTheMax said:
Very nice, if you don't mind not having gsync/freesync this makes a very nice option, Since I converted to using a Sammy TV as a monitor I've had no regrets. PC monitors are seriously overpriced now versus these mass market TV's.

Couldnt agree more with this. I am currently looking for 3 screens to do a racing sim setup, Now its a while since I have bought screens and it has become more of a minefield than ever.
Input Lag is the new Buzz word around screens, Last time I bought one Hz was the latest big thing and before that it was response time.
REALLY are we not being suckered in to some awesome marketing bull with PC monitors.
I dont hear PS4 or XBOX one owners raging about Hz and input lag with their tv screens or for that matter any pc users a few years back.
Do we really need our displays to have absolutley the best numbers for all of these specifications ???????
I for one will be buying 3 x 32" TV's for a fraction of the cost of 3 super duper 144hz zero input lag monitors and I firmly believe I will still enjoy my racing sims just the same
 
AGreed input lag can be too big of a thing. So long as its reasoanble and not into 100s of ms then its fine.

As I have staed previous there are a lot of current high end £1000+ pc monitors all with input lag worse than some Tvs yet pc owners are still buying them in their droves and dont seem concerned with the input lag..............

Maybe for competitive fps playing but then they want 1080p not 4k and hgih frequency as well so wouldnt even be buying the 4k monitors anyway.
 
Had mine delivered today but can't have a play until I've finished work at 8.

Demon. Any chance you would be willing to post up a brief overview of your settings, please? It'd be cool to use them as a place to start and then tweak to taste from there.

Nice review i wonder what power usage (watts) is like between using a tv as a monitor and using a proper pc monitor anyone know

Absolutely no different IMO, I've just measured mine to confirm and compared to the Philips BDM4065 UC as measured by TFT central: http://www.tftcentral.co.uk/reviews/philips_bdm4065uc.htm)

Philips BDM4065UC:
Manufacturers Quoted Consumption = 77.6W
Measured at manufacturers settings = 81W
Measured at Calibrated Brightness (120 Lumens) = 45W

My figures:
Samsung 40KU6400 Quoted = 62W
Measured at manufacturers settings = 66.5W
Measured at Calibrated Brightness (120 Lumens) = 47.1W

No probs:

PC Setup
Input set to 'PC' (Highlight the HDMI 'source' icon and press up, then edit, then select PC)
Picture Mode - Standard
Special Picture Mode - This says 'SPORTS' but is actually turned off when you drill down in that menu.

Expert Picture Settings:
Backlight - 8
Brightness - 49
Contrast - 99
Sharpness - 50
(Everything is now greyed out between this and the next option)
HDMI UHD Colour -> HDMI the PC is connected to is 'ON'
(more greyed out stuff)
Colour Tone - Warm 2
White Balance -> 2 Point ->Red Gain 14 / G Gain -3 (all others 0)
Gamma - 0

When you select 'PC' as the input type a lot of stuff is greyed out so there isn't any other adjustments to make.

This is for 2.2 Gamma, 120 Lumens, D65 white point which is the normal monitor calibration target as per TFT Central etc.

You, sir, are a star! Just about to open the box.

Cheers.
 
Hi all,
Really interested in this monitor but some reviews say that motion can get blurry and jutter during movies, does this have any impact when using it as a monitor for gaming.

Two things on this subject
1. PC Monitors offer no video processing of note, and when set in PC mode on the Samsung it acts as 'dumb' as a PC Monitor in that regard, i.e. as with a PC Monitor, supply it 60fps and it's 'smooth', supply it 25hz and it'll look like a PC monitor would, jerky..

2. It actually has quite good motion smoothing processing options if you set it up as a TV and play things like Amazon prime through it. I think the comments in reviews are really comparing it to TVs costing 2-3 times as much which handle a wider range of odd ball cases, like 24Hz where motion handling needs extensive processing.

I've actually been impressed with it's motion handling in video, and I've even turned it on when playing 30fps games on the Xbox for a much smoother rendition, although I find the input lag intrusive so switched the motion processing back off for that.

Thankyou for this post! - I WAS waiting to get the LG 38" ultrawide, but im seriously thinking of this and save some serious cash!! Apart from day to day usage of pc i have a ps4 connected and i only have various simulators and low intensive games so maybe ideal!... 2 questions though if someone can help?

1. Is there a curved version of this? - Plenty of ones about but i want to make sure the insides are the same?? (Looked at KU6100/KU6670 - but thats 43" as 2 examples??) - but no curved version is not a deal breaker for me...

2. Also is a 970 going to be enough to power it?? - The cash saved helps towards a 1080 i want but they are still to much for me at the mo....

Ta :)

I gather that the KU6500 series is the same screen but curved, and as for the 970 it should do ok on Low-Medium for most things :) 4k is VERY demanding ;)


edit - I'm also looking at getting the 65" version of this baby :cool:

Yeah i know i need to update the graphics card.... hopefully to a 1080ti if its out when im ready! Im prepared to make do with the 970 for a while...Appreciate the heads up on KU6500.. Thanks :)
 
Thanks for adding the picture, I think its made my mind up to go this route :)

Is it an easy thing to run a superwide resolution then? I've only got a 980 (for now) so I've little chance of running stuff at 4k
 
I thought I'd try Gears of War 4 on PC to see what my GTX970 could do, and I was not surprised that 4k requires lowish settings which make the game look terrible, so I messed with the settings and for a rock solid 60fps, it will handle 2160 x 1440 on Ultra with the dynamic resolution set to 50%.

Absolutely so much more playable than the consoles 30fps, and slightly improved IQ throughout even at double the framerate.
